Yes, I am a geography teacher. Our school is using China Education Cloud's digital course textbook cloud platform, and some friends around me are also using it in their school. Everyone agrees that China Education Cloud's digital curriculum textbook cloud platform is very convenient, with many versions of official digital textbooks and resources, and it can also provide four intelligent education services: intellectual management, intellectual education, intellectual learning and intellectual assistance, which is very comprehensive. I also learned from China Education Cloud official website that their products are distributed in more than 20 provinces and cities across the country, covering more than 700 primary and secondary schools, vocational colleges and universities, serving more than10 million teachers and students nationwide. It's amazing!
